TIRE.

Specification of Letters Patent. Patented; Sept. 21.,

Application filed-December 23, 1907. SerialNo. 407,740.

Toicll whom it may concern:

Be it known that 1, Joint S. STEVENSON, a-

citizen of the United" States of America, re-

siding at Detroit, in the county of Wayne and tate of Michigan, haveinvented cer-.

tain new and useful Improvements in Tires, of which thefollowingis aspecification, ref

erence being had therein to' the accompanying'jdrawings.

The invention relates particularly to a.

wheel for automobiles, v and more especially to a punct'ure-proof tiretherefor, and it. eonsists'in the novel and. peculiar 'construction ofthe tire and {in the arrangement and combination of thevarious parts, aswill be more fully hereinafter set forth.

In. the drawi central cross-section through a-portion of a vehicle wheelembodyin my invention; and 2-is a view in side e evation thereof.represents theusualhub of the wheel, B the spokes and C. theif ellyr I.D isja rim,--preferably of metal,-fitted about the'felly, and 'E is an.':.iter rim,-spaced from-the inner,;about which is encircled a tire ofhard rubber-or other similar material F. Interposed' between the tworims is a yielding abnt;nent,preferably in the form of a-pneumatic tubeG,and H is a sectional covering for the'tube. This covering is pref.-erably composed of two annular members a and b of anysuitable material,such as canvas or rubber, having the body portions intermediate'the rimsconcaved as at a, andthe' upper and lower portions 03 flat so as to abutagainst'the inner and outer faces respectively of the .outer and-inflerrims. The cover sections are also formed with annular hookshapedsections 6 and f adapted to engage hook-shaped flanges hereinafterdescribed upon the rims, the engagement of the rim flanges and the coversectionsserving to hold the parts in their proper relative positions.

The inner rim D is formed preferably with an outwardly-projectingmarginal flange 1. integral in this instance with'the rim and fashionedon its inner face to form a' hook adapted to engage the adjoininghook-shaped section'of the covering. J is a similar flange at theopposite edge or margin of this rim and detachably connected thereto.The rim is further provided with inwardly-extending an ular lug sectionsa b seated in grooves or recesses formed in the folly for that pur pose.The detachable flange J is secured to the lug sections 7) by suitablescrews or other s,- Figure 1 is a vertical fastening devices 9.. Theouter rim llis p'rovided' with similar marginal. flanflesl'i and Lrespeetlvely integral with and detachable from the rim, and the .rimcarries the usual out-turned channel flanges M, between which the tire Fis seated,,the marginal flange L being det-achably connected to one'oithese 'channel flanges as indicated.

To prevent relative sidewise movement of the rims, guide flanges areemployed adapted. to engage annular flange guides. the flanges beingpreferably carried by one of the rims and the guides by the other asindicated. I

have here shown the guide flanges O detach ably connected to themarginal flanges'of the outer rim E and theflange sockets or guidescarried by the inner rim and formed preferably by, annular flanges Pspaced i i-om the marginalrim flanges by lugs s projecting'ilaterallyfrom the lattenand detachahly eongnecte'd by securing devices iInpractice, the pneumatic tube intermediate the rims acts in the samemanner as the ordinary pneumatic tire, giving the desired resiliency andabsorbing the shocks and j ars whlle at the same time 1t is etfectlt'elyprotected from injury, the rim sections. and flanges and guidesassociated therewith forming a sectional-radially yielding housing inwhich the pneumatic tube is inclosed.

hat I claim as my invention is,-

1. In a vehicle wheel, the combination with a. felly, ofspaced inner andouter rims thereon, each of said rims being provided with inwardlyandoutwardly projecting marginal flanges, the inwardly projecting flangesof. the one and the outwardly projecting flanges of the other beinghook-shaped, and one of each of said outwardly and inwardly projectinghoolcshaped flanges, being detachable, coiiperating guide flangesdetachably secured respectively to the hooked flanges of the outer rimand to the inwardly projecting flanges of the inner rim, a tireinterposed between the rims, a sectionalcovering for the tube flanged toengage the hook-shaped "flanges, and a tire encircling the outer rim andseated between the outwardly projecting marginal flanges.

2. In a vehicle wheel, the combination with a felly, of spaced inner andouter rims thereon, each of said rims being provided with inwardly andoutwardly projecting marginal flanges, the inwardly projecting flangesof the one and the outwardly projecting flanges of the other beinghook-shaped, and

one of each of said outwardly and inwardly taehably carried by thehooked flanges of:

one rim, the'inwardly projecting flanges of the other rim havinglaterally projecting lugs, flanges detachably secured to said lugs andspaced from the hooked flanges of the latter rim whereby a guide isformed for the guide flanges of the'other rim, a tire interposed betweenthe rims, a sectional covering for the tube having portions engagingsaid hook-shaped flanges, and a tire encircling the outer rim and seatedbetween the outwardly projecting marginal vflanges.

In a vehicle Wheel, the combination With a telly,- of spaced inner andouter rims thereon comprising oppositely disposed channelshapedmembers-corresponding in widthlto 20 the Width of the any, each havingits-body portion and side flanges formed in ash 1e integralconstruction, and beingprovi ed with hook-shaped fianges projecting.oppositely from the flanges of the chaimelg one. of each of saidhook-shaped flangesbein detachable, guide flanges detachably. secur toeach oflsaid rims for preventing relative sidewise movement; of thelatter, a yieldable abutment between the rims, and a tire encircling theouter riin In testimonywhereof I aihx my signature
